WALKING-BEAM FOR HAND-CARS.

SPECIFICATION forming part of Letters Patent No. 737,604, datedSeptember 1, 1903.

Application filed February 19, 1903. Serial No. 144,089. (No model.)

To all whom it may concern:

Be it known that I, PERRY J. GARRISON, a citizen of the UnitedStates,residing at the city of Three Rivers, in the county of St. Josephand State of Michigan, have invented certain new and useful Improvementsin Talking- Beams for Hand-Cars, of which the following is aspecification.

This invention relates to improvements in walking --bea1ns for hand carsand in the method of manufacturing the same.

The objects of the invention are, first, to produce a very strong andefficient hand-car walking-beam at a minimum expense, both as to laborand material; second, to provide an improved construction of hand-barwalkingbeams which can be readily formed from a blank of sheet metalinto one continuous piece, thereby avoiding the numerous objectionablewelds which appear in hand car walkingbeams as now generallyconstructed.

Further objects will definitely appear from the detailed description tofollow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure. embodying the features of my invention is fully illustratedin the accon1- panying drawings, forming a part of this specification,in which- 7 Figure 1 is a detail view of the blank of sheet metal fromwhich the hand-car lever or walking-beam is produced. Fig. 2 is aninverted plan view of the completed lever or walking-beam, showing theformation of the various parts. Fig. 3 is a side elevation View of thestructure appearing inFig. 2, bottom side up. Fig. 4 is a detailsectional View taken 011 a line corresponding to lines 4 4 of Figs. 2and 3, showing the formation of the central portion of the lever.

Referring to the lettered parts of the drawings, the body portion A isdivided into arms A A, forming a fork at each end. The main body of thelever is formed by folding its sides upon itself, whereby the ears 0 0will extend down and be perforated at c to attach to the pivot on thestandard of the hancbcar. Longer ears D D toward one end also fold downparallel, as appears in Figs. 2, 3, and 4, and are perforated at d,forming the pitman connection to the walking-beam for the actuation ofthe hand-car running-gear.

Blanks B B at each end are struck up into eyes B B before the body partof the lever is folded, and these arms are bent outwardly to give asupport for the cross-bar or handle at each end, thereby affordingefficient sup port for the handle, the holes I) being formed through thesame for that purpose.

By this methodit will be noted a walkingbeam for a hand-car is formed inwhich there are broad flanged eyes B B at each end and that the :leveris formed in as strong a manner as possible by the sheet metal beingfolded upon itself, thereby giving an extraordinary strength to thesame, owing to this fold of the body of the lever through the middleportion.

The lever or walking-beam thus formed is very efficient and finished inits appearance as well, and it is obvious that the material is disposedof in the best possible manner to resist the strains that come upon it.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A walking-beam or lever for a hand-car, formed of a sheet of metalwhich is forked at each end, with eyes struck outwardly in the ends ofthe forks, and the central portion folded upon itself, and beingprovided with doWnwardly-projecting ears suitably perfo rated forattachment to the standard of a hand-car and to connect the pitman-rod,for the purpose specified.

2. A Walking-beam or lever for a hand-car formed of asheet of metalwhich is forked at each end, with its central portion folded uponitself, the arms being suitably perforated to receive the cross-bar, andthe folded part being perforated for connections to the standard andpitman, for the purpose specified.

3. A walking-beam or lever for a hand-car, formed of a single piece ofsheet metal, folded upon itself at the central portion and forked ateach end to receive the cross-bars, for the purpose specified.

In witness whereof I have hereunto set my hand and seal in the presenceof two witnesses.
